Mlodinow spoke at the RSA recently - the first video (I highly recommend the podcast, link included below, for the full conversation) - and as part of the Authors@Google series (a longer talk on his part). Both videos are presented below.

Every aspect of our mental lives plays out in two versions: one conscious, which we are constantly aware of, and the other unconscious, which remains hidden from us. Over the past two decades researchers have developed remarkable new tools for probing the unconscious, or subliminal, workings of the mind. This explosion of research has led to a sea change in our understanding of how the mind affects the way we live. As a result, scientists are becoming increasingly convinced that how we experience the world--our perception, behavior, memory, and social judgment--is largely driven by the mind's subliminal processes and not by the conscious ones, as we have long believed.
